APPARATUS FOR FORMING SHEDS IN LOOMS ELECTRICLLY.

SPEGIFIGATION forming part of Letters Patent No. 515,775, dated March 6, 1894.

Appunti-.ion nea prix so, 1892.

To @ZZ whom, it may concern.-

Be it known that I, JOSEPH KAUFEMANN, a

, Vsubject of the King of Prussia and German Emperor, residing at Hanover, in the Kingdom of Prussia, Germany, have invented cer tain new and useful Improvements in Apparatus for Forming the Sheds in Looms Electrically, of which the following is a specification.

In lieu of producing a pattern in weaving by means ofl Jacquard cards, in this invention, the pattern is woven directly from the pattern sheet containing it, while the transferring of the pattern from the .pattern sheet onto the goods is performed as usual through raising and lowering the Warp threads. The movement in itself is effected by connecting or disconnecting an electric current.

In order that my invention may be more fully understood, I have caused to be appended hereunto one sheet of drawings marked with letters of reference indicating like parts in the various figures.

Figure I is an end view of the arrangement for transferring the pattern from the pattern sheet to the loom. Fig. 2 is a side viewthereof. Fig. 3 showsthe Working of the Warp threads in another manner than that shown in Fig. l.

In carrying out my invention and referring to the figures generally, a is a metal roller mounted in a non conducting support.

'Above this roller moves' an endless pattern ment of the pattern sheet, the circuit is completed through the roller when the springs c Serial No. 431,264. (No model.)

come into contact with the said conducting roller a. The armatures e are then attracted and these armatures are connected with the warp threads of a loom, so that they are raised and lowered exactly according to the pattern on the pattern sheet b and thereby the pattern in the fabric produced. In lieu of employing magnets d and armatures e, the movements may also be effected through a solenoid or the like. In Fig. 3 the solenoid core c is shown as connected with lever f, the free end of which is in direct connection with the warp threads.

The substantial utility of this invention is that the large number of cards for the production of a pattern may be dispensed with and only one pattern sheet is required, and, that the pattern formation can be separated as may be desired, as the electricconnection between the contact springs and the magnets may be made as long as desired and one apparatus will serve simultaneously for several looms, as there may be several currents running from each contact spring.

Having now particularly described and ascertained the nature of this invention and in What manner the same is to be performed, I declare that what I claim is In combination, the series of magnets with their armatures, the positive connections intermediate said armatures and the healds whereby the movement of the armatures Will raise or lower the Warps, and the means for energizing and cle-energizing the magnets consisting of a cylinder, a pattern sheet carried thereby, one of said parts being a conductor and in the circuit, and the other a nonconductor, the movable contacts in the circuit and the electrical circuit, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
